The object of the invention is to provide improved constiiietion foi' holding" the end@ o" the colhipsihle sections in expanded position.

AThe invention is iiliitizited lin the iiccoini'niiiying drawings in which Figure 1 iS vertical section oi part oi' a i'iin provided wiin the invention. Fig. 2 is ii plnn oi' Fig. i.. l ifi :i longitudinal section fhoiving` the innnnei oi' breaking oi' essei'nhiing the parte'.
